Be it known that l, ALFRED r. eri-en, in the county of Trnn it of Ohio, have invented eertoili no ful Improvements in Feeding Mechanism for Printing-Presses; and I do hereby declare the following to be a lull, elem, o zsot desoription of the invention, such 7 ll enable 1 others skilled in "the art to whim it at; 1'0 wins to make and use the same.

The primary object of this imres provide lnlpl'OVGL means for ins register of stock, not only rel grippers, but also as to the ty being of primary importanee i1. :mnltiex Work.

A further object is to remoi oriinps in the paper and flatten it o the impression-oylintier.

The invention will he liere nza and use- .mesteo in u N in l ter forth, and pzirticnlsrlyv point out r i i e e eh i X 1 o? sn BI' claims.

I claim as my IIW'GIIUOH 1. The combination with a printing-press having an impression-eylinder, and grippers on the latter, of means for supplying a blast of air against the front end of each piece of stock as it is brought into position to be engaged by said grippers.

2 The ooi-nbination with a printing-press having an impression-cylinder, and grippers I on the latter, of a pipe paralleling said oylinder and. arranged in juxtaposition to the point at Which the stock is engaged by said grippers, said pipe having openings in its ogver face. and means for supplying a blast oi air through said pipe against the front end of the stock as it is brought into position to g be engaged by said grippers.

In testimony whereof I have signed this specification in th pres-nee of two subscribing Witnesses.
